LEWIS W. SNOYVDEN, OF TILDEN, TEXAS.

CACTUS-BURNER.

SPECIFICATION forming part of Letters Patent No. 657,036, dated August 28, 1900.

Application filed October 21, 1899. Serial No. 734,311. (No model.)

To @ZZ whom t may concern:

Be it known that l, LEWIS W. SNOWDEN, of Tilden, in the county of McMullen and State of Texas, have invented a new and useful Improvement in Cactus-Burners, of which the following is a specification.

My invention is an improvement in cactusburners which are used to destroy the spines or thorns of the cactus or pricklypear, so as to render the same more useful as a food for cattle.

One object of the invention is a burner for this purpose which will produce an intense flame and which will thoroughly vaporize the gasolene or other volatile fuel, so that none of it is wasted.

A further object of the invention is a burnernozzle so arranged that a regulated draft may be created therethrough to form a hollow or annular ame and which will spread the llame over the vaporizing coil, the nozzle being further arranged so that the downdraft therethrough may be caused to blow out of lthe nozzle-tip any impurities or scales which are liable to collect therein.

A further object of the invention is a hood for confining the flame to the vaporizing-coil until every part of the same has been thoroughly heated; and a further object of the invention is an improved coil which allows the flame to act on the liquid fuel passing through it while the liquid is passing down-l ward and upward through the coil, thereby causing it to be thoroughly vaporized by twice getting the benefit of the llame.

The invention consists in certain details of construction and arrangement of the parts,

which I shall first describe and then particularly point out in the accompanying claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which like characters of reference indicate corresponding parts in all the views in which they occur.

Figure l is a perspective View of my improved cactus-burner shown in use. Fig. 2 is a detail side elevation of the vaporizingcoil and burner-nozzle and a vertical section of the hood. Fig. 8 is a horizontal section taken on the line 3 3 of Fig. 2. Fig. 4. is a detail vertical section of the nozzle, taken on the line 4. a of Fig. 2. Fig. 5 isa side elevation of a slightly-modified form of coil.

through which the fuel is forced, and a vaporizing-coil and burner C. As shown in Fig. l, an outlet-pipe a extends forwardly from the lower end of the tank A in a curved direction and has a stop-cock as at its forward end in easy reach for manipulation. An airpump a4 is secured to the side of the tank and is adapted to pump air into the tank to force the fuel out under pressure.

Attached to the forward extremity of the outlet-pipe ct is a stout rubber or other liexible tube B. which is in turn connected securely to the rear end of the tubular handlerod B; preferably for convenience formed in two detachable sections h and b. To the free end of the forward section b one terminal of my improved coil C is secured by threaded engagement or other suitable means. This improved coil is formed of a suitable piece of metallic tubing doubled together at the lower end of the coil and forming when thus doubled the convolutions of the coil up to a point a short distance above the middle of the coil, when one end c of the tubingis separated from the other and is extended to form a terminal at approximately right angles to the axis of the coil, while the other end o forms single convolutions from such point to form the remainder of the coil and is extended parallel to the axis of the coil to form the other terminal. On the upper end 'of the terminal c' is screwed the elbow c2, and a nipple c4 on the burner-nozzle c3 of improved construction is screwed in the other end of the elbow. The body of the nozzle has a lateral.`

opening c5, leading from the nipple c, and

an annular passage c, leading out through the tip c7.

Above the passage o6 the body of the nozzle is formed with an interior thread in whichV works a threaded hollow needle-valve et,

The lower tapered end of the provide the hood D, which is divided or split throughout its length and has crimped edges d', adapted to interlock when the hood is inserted over the coil, an opening d2 being formed in the hood for the passage of the terminal c, and L-shaped or angular ribs d being secured at equal distances apart in the hood to hold the latter spaced from the coil,`

as seen best in Fig. 3.

As shown in Fig. 2, the metal tubing forming the coil C is spaced apart at the bend c, and another turn of the tubing is placed in the bend, so as to provide against'the contingency of the said bend c from droppingdown when the coil is very hot, while in the coil C (shown in Fig. 5) the bend on the outside, as shown.

In practical operation the air above the liquid fuel in the tank A is compressed, so that the fuel will be forced under pressure through the handle-rod B and vaporized in the coil C, the vapor burning at the nozzlel c3 and the flame being directed by manipulating the handle-rod.

It should be observed that by formingy the nozzle independent of the coil and detachably connecting them they may be separated at, any time for the purposes of repair or thev like, that by establishing a downdraft through the nozzle the flame will rbe directed to the coil, that by forming the, coil double forv a portion of its length, as described, the fuel will get the benefit of the iiame both going down the coil and returning upl through the coil, and that by bringing the terminal e out of the coil just above the middle thereof the weight of the coil below the terminal is oo m-n pensated for by the weight of the coil above the terminal together with the nozzle, so that, the handle-rod can be easily turned about its longitudinal axis, therebyv rendering the manipulation of the device easy. It should also be noted that ifv any impurities collect in the tip of the nozzle they may be easily, blown out by screwing the valve' e8 away from the tip of the nozzle, when the draft will blow the impurities out of the tip, thus doing away with the necessity ofl removing they nozzle. to clean it.

It is to be understood that the needle-valvel c8 while primarily intended to prov-ide a draft and to regulate the size of the annular` flamev also completely shuts off the llame when screwed down tightly in the nozzle.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a cactus-burner, a vaporizing-y coil formed of a doubled piece of tubing, one end of said tubing extend-ing from the coil approxr.

mately at right angles tothe axis thereof, andv j om is, left having double convolutions for a portion of :its length and a terminal extending out from the coil at upper termination of said convolutions, the other terminal forming the remainthe other end being @oiled above the rSfnamed end, the tubing being spaced apart at its bend at Ythe lower end of the coil and receiving another bend of the tubing therebetween, ,as and for the purpose Set forth- 2. In a cactus-burner, a vaporizing-coil formed of a doubled piece of tubing, one end of said tubing extending from the coil approximately at right angles to the axis thereof, and the other end being coiled above the firstnamed end with its terminal extending parallel with the axis of the coil, as set forth.

'3. In a cactus burner, a vaporizing-coil consisting of tubing formed with double convolutions for a portion of its length and one terminal extending from the upper end of the double convolutions, the other end of the tub- 1 ing beingcoiled singly above the double con- `voglutienfs and forming the other terminal, as

set forth.

4t. In a cactus-burner, a vaporizing-coil der of the coil and extending upwardly, and a burner-.nozzle secured on the latter terminal, as set forth.

In a cactus-burner, a vaporizing-coil whose one terminal extends out from a con- `voltltien near the middle of the coil and whose other terminal extends upwardly above the coil, av burner-.nozzle on said latter terminal,

,and a split hood open at both top and bottom lld having an aperture in its side near its middle in which the first-named terminal is adapted tebe inserted, said tube being formed with interlocking edges, and L -shaped longitudinally-extending ribs secured in the head and adapted to space the latter from the coil, as s et forth.

6. In a cactus-,burnenthe combination with a tank and a delivery-tube connected therewith and forming a handle-rod, of a Vaporizlthereof and being coupled to the handlesrod,

the other end of said tubing being coiled above the first-named end and extended upwardly parallel with the longitudinal axisof the coil,

la burner-.nozzle having a lateral nipple secured by an elbow to thel upwardly-extending .end of thecoilf, and having its outlet pointing toward the coi-1, and a hollow needle-valve screwing in said nozzle and having a handlev at its upper end, as and for the purpose set forth.

In testimony whereof I have signed my nameI to this specification in the presence of l two subscribing witnesses.
